On my “test” machine it has taken me a good 20 min to compile this thing.
Dell Insperon 1100
1 x 1000Mhz Celeron Processor (i486)
374MB of RAM
(I will say I do love that machine though it allways does what it is told.)

On (one of my) actualy nice computers it took 30 seconds.
HP ENVY dv7
8 x 3Ghz CORE i7 (yes yuck it is an intell but it was on sale so. . .)
12GB of RAM
